📰 ArXiv cs.AI
Rethink structured reasoning failures by focusing on model capacity, not format, to improve performance
Action Steps
- Separate format-specific effects from prompt-length confounds in your model evaluation
- Use information-matched prose controls to isolate the impact of structured formats
- Apply a schema complexity gradient to assess model performance across varying levels of complexity
- Evaluate model capacity as a primary factor in structured reasoning failures
- Optimize model architecture and training to increase spare capacity for improved performance

Title: Capacity, Not Format: Rethinking Structured Reasoning Failures
Abstract:
arXiv:2606.09410v1 Announce Type: new Abstract: Prior work treats structured output as a reasoning tax, but this framing is incomplete: the cost of formatting depends strongly on a model's spare capacity. Using information-matched prose controls and a four-level schema complexity gradient, we separate format-specific effects from prompt-length confounds across 4 models and 5 benchmarks with 0% parse failures on successfully generated responses. We find that structured formats are capacity-depend
